Abstract
A photonic integrated circuit (PIC) includes photonic components fabricated on the PIC. One of the photonic components includes an optical coupler configured to optically couple to an optical component. The optical coupler includes waveguide elements arranged in a 2-dimensional array that is configured to provide a first mode having a first shape chosen to match a second shape of a second mode of the optical component.
